start_devserver: update relative paths in command line flags

start_devserver: update relative paths in command line flags

Because this scripts changes directory, it's possible for relative
paths to be incorrect when read by the actual dev server. This fixes
the issue by prepending the current working directory to relative path
args.

Does it make sense to use "realpath" instead? If the arg starts with "./" or
"../" ([[ $blah == ./* ]])

made some fixes: use realpath, handle args w/ = in them. PTAL. thanks

... still looks hacky... how about moving this logic into devserver.py? you can
pass the original CWD as an argument from the shell script. and devserver.py can
apply it only to the relevant arguments.

I see your good cleanup suggestion and raise you one more :)

Looks like the 'cd' in this script has been there since it was moved out of the
dev server dir itself. The dev server seems to already support being called from
outside it's dir, and I double-checked w/ args --image and --payload.

So, this seems like a good solution.
